Melanie emptied her piggy bank and made stacks of coins using all of the quarters. She has one stack of 8 quarters, three stacks of 4 quarters, and one stack of 6 quarters. The expression 8+3x4+6 can be used to represent Melanie's stacks of coins.

Determine the total number of quarters that Melanie had in her piggy bank.

How much money did Melanie have?

26

Step-by-step explanation:

using the order of operations we do 3x4 to get twelve then go from left to right. 8+12+6. 8+12 = 20. 20+6 = 26.

$4.50

Step-by-step explanation:

4 quarters= $1

8 quarters= $2

6 quarters= $1.50

so, 1 + 2 + 1 = 4

plus 50 cents

$4.50
